Mini-EDACS: Development of the Eating and Drinking Ability Classification System for young children with cerebral palsy.

Aim: To develop and test Mini-EDACS to describe developing eating and drinking abilities of children with cerebral palsy (CP) aged between 18 and 36 months.
Method: The existing Eating and Drinking Ability Classification System (EDACS) was modified to define Mini-EDACS content. Mini-EDACS was developed in three stages: (1) EDACS was modified after application to videos of standardized feeding evaluations of children with CP aged 18 to 36 months (n = 130); (2) refined content and validity of Mini-EDACS was established through an international Delphi survey; (3) interobserver reliability was assessed by comparing Mini-EDACS levels assigned by speech and language therapists (SaLTs) from video data and parent report.
Results: Mini-EDACS provides age-appropriate descriptions for children aged 18 to 36 months with CP. Eighty-nine stakeholders participated in the Delphi survey; required levels of agreement were met after one round (i.e. >80% agreement). Thirteen SaLTs completed paired ratings from 43 video recordings: absolute agreement was 58% (kappa 0.43; intraclass correlation coefficient 0.78; 95% confidence interval 0.63-0.87).
Interpretation: Mini-EDACS provides a valid system for classifying eating and drinking performance of children with CP under 3 years old. Results suggest moderate agreement and good reliability when rating Mini-EDACS levels from video recordings of young children with CP.
